Beginning AutoCAD 2015. Cheryl R. Shrock

to simulate a 3D object by aligning along 3 axes, these are Top, Right and Left, called Isoplanes. When the button is enabled you can toggle the Isoplanes by pressing the F5 key. Isometric Drafting is discussed in the Advanced AutoCAD Workbook.

      OBJECT SNAP TRACKING (You may also use F11 to toggle ON or OFF)

      Object Snap Tracking controls the display of object snap reference lines, AutoSnap marker, tooltip and magnet.

      2D OBJECT SNAP (You may also use F3 to toggle ON or OFF)

      When 2D Object Snap is ON the cursor will “snap” to preset locations on 2D objects. More on this in Lesson 4.

      LINEWEIGHT

      Lineweight displays the width assigned to each object. When it is ON the lineweights are visible. You can change the lineweight settings by clicking on the down arrow and selecting Lineweight Settings. More on this in Lesson 3.

      TRANSPARENCY

      When Transparency Show/Hide is ON all transparent layers will be displayed. If it is OFF no layers will display as transparent. More on this in Lesson 3.

      SELECTION CYCLING

      Selection Cycling allows you to select objects that are overlapping. This is most useful when creating 3 dimensional models discussed in the Advanced AutoCAD Workbook.

      3D OBJECT SNAP (You may also use F4 to toggle ON or OFF)

      When 3DOsnap is ON the cursor will “snap” to preset locations on 3D objects. This option will be discussed in the “Advanced AutoCAD Workbook”.

      DYNAMIC UCS (You may also use F6 to toggle ON or OFF)

      Dynamic User Coordinate System changes the grid plane to follow the XY plane of the dynamic UCS. Used for 3D, refer to the Advanced AutoCAD Workbook.

      SELECTION FILTERING

      Selection filtering allows you to filter whether certain faces, edges, vertices or solid history subobjects are highlighted when you roll over them, very useful in complex 3D.

      GIZMO

      Gizmo tools help you move, rotate, or scale an object or set of objects along a 3D Plane, and discussed in the Advanced AutoCAD Workbook.

      ANNOTATION VISIBILITY

      When switched ON the Annotation Visibility tool displays or hides the visibility of annotation objects at the current scale.

      AUTOSCALE

      When switched ON the AutoScale tool Automatically updates annotative objects to support the annotation scale when the annotation scale is changed.

      ANNOTATION SCALE

      The Annotation Scale tool displays the current annotation scale. You can change the scale by clicking on the down arrow and selecting from the list of predefined scales or you may create a custom scale. You can also display the scale in percentages by selecting Percentages from the list.

      WORKSPACE SWITCHING

      Workspace Switching allows you to change the workspace environment, you can choose between “Drafting & Annotation”, 3D Basics and 3D Modeling. You can change the Workspace by clicking on the down arrow and selecting from the list.

      ANNOTATION MONITOR

      Provides feedback regarding the state of associative annotations when using parametric dimensioning. This option is discussed in the “Advanced AutoCAD Workbook”.

      UNITS

      The Units tool allows you to change the display style of the Drawing Units. You can choose between Decimal, Architectural, Engineering, Fractional and Scientific. You can change the drawing unit display by clicking on the down arrow and selecting from the list.

      QUICK PROPERTIES

      If ON, Quick Properties displays the properties of the object selected. If OFF the Quick Properties box will not appear. More on this in Lesson 12.

      GRAPHICS PERFORMANCE

      The Graphics Performance tool examines your graphics card and 3D display driver and determines whether to use software acceleration or hardware acceleration. You can change the performance settings by right-clicking on the tool button and selecting Graphics Performance, then change any settings required in the dialog box.

      ISOLATE OBJECTS

      You can choose to isolate objects by keeping them visible on the screen, all other objects will be hidden. Or you can choose to hide objects. To isolate or hide objects, left click on the Isolate Objects tool button and select either Isolate Objects or Hide Objects from the list. To restore all hidden objects left click on the Isolate Objects tool button and select End Object isolation from the list.
